[PATCH OLK-5.10] mm/writeback: fix possible divide-by-zero in wb_dirty_limits(), again
by Ze Zuo 10 Apr '24

10 Apr '24

From: Zach O'Keefe <zokeefe(a)google.com> stable inclusion from stable-v5.10.210 commit 81e7d2530d458548b90a5c5e76b77ad5e5d1c0df category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2EC CVE: CVE-2024-26720 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 9319b647902cbd5cc884ac08a8a6d54ce111fc78 upstream. (struct dirty_throttle_control *)->thresh is an unsigned long, but is passed as the u32 divisor argument to div_u64(). On architectures where unsigned long is 64 bytes, the argument will be implicitly truncated. Use div64_u64() instead of div_u64() so that the value used in the "is this a safe division" check is the same as the divisor. Also, remove redundant cast of the numerator to u64, as that should happen implicitly. This would be difficult to exploit in memcg domain, given the ratio-based arithmetic domain_drity_limits() uses, but is much easier in global writeback domain with a BDI_CAP_STRICTLIMIT-backing device, using e.g. vm.dirty_bytes=(1<<32)*PAGE_SIZE so that dtc->thresh == (1<<32) Link: https://lkml.kernel.org/r/20240118181954.1415197-1-zokeefe@google.com Fixes: f6789593d5ce ("mm/page-writeback.c: fix divide by zero in bdi_dirty_limits()") Signed-off-by: Zach O'Keefe <zokeefe(a)google.com> Cc: Maxim Patlasov <MPatlasov(a)parallels.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Ze Zuo <zuoze1(a)huawei.com> --- mm/page-writeback.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/page-writeback.c b/mm/page-writeback.c index b72da123f242..e969667e8d62 100644 --- a/mm/page-writeback.c +++ b/mm/page-writeback.c @@ -1519,7 +1519,7 @@ static inline void wb_dirty_limits(struct dirty_throttle_control *dtc) */ dtc->wb_thresh = __wb_calc_thresh(dtc); dtc->wb_bg_thresh = dtc->thresh ? - div_u64((u64)dtc->wb_thresh * dtc->bg_thresh, dtc->thresh) : 0; + div64_u64(dtc->wb_thresh * dtc->bg_thresh, dtc->thresh) : 0; /* * In order to avoid the stacked BDI deadlock we need -- 2.25.1

[PATCH OLK-5.10] btrfs: dev-replace: properly validate device names
by Long Li 10 Apr '24

From: David Sterba <dsterba(a)suse.com> stable inclusion from stable-v5.10.167 commit 2886fe308a83968dde252302884a1e63351cf16d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E469 CVE: CVE-2024-26791 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- commit 9845664b9ee47ce7ee7ea93caf47d39a9d4552c4 upstream. There's a syzbot report that device name buffers passed to device replace are not properly checked for string termination which could lead to a read out of bounds in getname_kernel(). Add a helper that validates both source and target device name buffers. For devid as the source initialize the buffer to empty string in case something tries to read it later. This was originally analyzed and fixed in a different way by Edward Adam Davis (see links).

[PATCH OLK-5.10] dm-crypt: don't modify the data when using authenticated encryption

From: Mikulas Patocka <mpatocka(a)redhat.com> stable inclusion from stable-v5.10.211 commit 3c652f6fa1e1f9f02c3fbf359d260ad153ec5f90 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E2LW CVE: CVE-2024-26763 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 50c70240097ce41fe6bce6478b80478281e4d0f7 upstream. It was said that authenticated encryption could produce invalid tag when the data that is being encrypted is modified [1]. So, fix this problem by copying the data into the clone bio first and then encrypt them inside the clone bio. This may reduce performance, but it is needed to prevent the user from corrupting the device by writing data with O_DIRECT and modifying them at the same time.
